<p>Once everything is ready, I try to move the two axes, each independently. Here is the sample video, and through the video conference of witness Alvaro, waiting to move on to the programming and electronic part. Thanks to Pablo my instructor who acted as camera director. 🤗</p>
<p>Once the <b>Arduino Mega 2560</b> has been programmed (without connecting the RAMPS module); I connect the <b>RAMPS</b> where there are three <b>Polulu Drivers (HR4988).</b> We are only going to use two axes, in our case X and Y. By the GRBL software configuration, that connection is on the X axis and on the Z axis (this can be modified in the code). The RAMPS is powered by a <b>12V, 10A power supply.</b> This is the physical connection.</p>
<p>When we started testing the machine, we realized that sometimes the machine was "lame". The part of the tool was raised. So I printed another support with the marble and put it to the end.</p>
<p>The machine was manufactured and configured in less than a week. It is something incredible, given the situation. 😊</p>
<p>But if we had more time, I would like to improve the end-effector. I would use a rack and pinion to raise and lower the marker and that would not mark the page, when it makes the trajectory in the air. I would also like to try using other tools, apart from the marker. Same as using a litter box and moving the sand with an awl, or marking the modeling clay.</p>
<h1>Conclusions</h1>
<p>Given the situation and the moment we are going through all over the world, I am very <b>proud of this team.</b> 🤗</p>
